Copy performance test

A common everyday scenario is simulated here. Three test folders are created:

  • ISO (folder with two large files)
  • Program (folder with many small files)
  • Game (folder with small and large files)

The three folders are copied using the Windows copy command (cache remains enabled). The real-world test from 24 August 2023 shows performance during simultaneous write and read operations. The lower the duration, the better.

Compression performance test

Here, speed is measured depending on how compressible the data is.

CrystalDiskMark Benchmark

Similar to AS SSD, two sequential and two random performance tests are carried out here and the write and read speed (manufacturer: 3500 MB/s and 2800 MB/s) the ADATA SSD is determined.

HD Tune Pro long-term test

A long-term test was performed to fully utilize the storage. You can see from when a possible cache is full and write performance drops. A test file of 300 GB was written to the medium. The exact cache size could not be determined because the test file did not exhaust (push to the limit) the cache. The test file could at least be read with an average read speed of 2,120 MB/s and written at 2,370 MB/s.

HD Tune Pro Benchmark

HD Tune writes a 5 GB file to the ADATA NVMe M.2 SSD. The transfer data of the read speed is displayed graphically. The minimum, maximum and average values are also determined. The measured access time and burst rate are also shown.

ATTO Disk Benchmark

Here, a 256 MB file is written to the ADATA NVMe M.2 SSD multiple times. The I/O block size varies (from 512 bytes to 64 megabytes). The larger the blocks, the faster writing and reading usually becomes.

SSD-Z Benchmark

Similar to HD Tune, a 500 MB file is written to the ADATA NVMe M.2 SSD here. The transfer data is displayed. The more consistent the line, the better. Unfortunately, the tool no longer works correctly from around 4,000 MB/s and no line is displayed (and sometimes incorrect min/max data is shown).
